DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a line structure for laying, on a laying surface such as a road surface, a line having projections for guiding a visually impaired person.

[0002]

2. Description of the Related Art Generally, in order to guide a visually impaired person on a road, a passage of a station, a platform, or the like, a relatively wide line made of a light color such as yellow is used so that a person with low vision can easily recognize it. A plurality of various projections are provided on this line to inform the visually impaired of the passage status. That is, on the line, a streak-like projection, a column, or a truncated cone-shaped projection is provided, and a visually impaired person is guided by the streak-shaped projection. It warns people with disabilities.

Conventionally, as a method of installing the above-mentioned line on a laying surface such as a road, a concrete block having a rectangular shape in plan view having a plurality of projections projecting from the upper surface is previously produced in a factory, and this block is installed on a construction site. A first method of embedding a plastic sheet in a rectangular shape in plan view having a plurality of projections protruding on an upper surface thereof, and a second method of sticking the sheet on the laying surface with an adhesive. Is commonly done.

Further, as disclosed in Japanese Patent Application Laid-Open No. 0-00000, for example, a third line is formed by using a hot-melt paint and using a construction machine to integrally form a line in which a projection is directly formed on a laying surface at a construction site. A method has also been proposed. This method
Equipped with a storage tank equipped with a line forming outlet on the construction machine,
When the hot-melt paint stored in the storage tank is allowed to flow out of the outlet to form a line, the outlet is intermittently opened and closed by an opening and closing body so that a projection is integrally formed on the line. It was done.

[0005]

In the first method, however, it is necessary to excavate the laying surface to bury the block, so that the construction work becomes large and takes a long time. There is a problem that costs are high.

Further, according to the second method, while the construction work can be performed easily and in a short time, it is technically difficult to affix the sheet to a laying surface made of asphalt, concrete or the like so as not to peel off. Yes, and poor durability. In particular, when the sheet is laid on a laying surface made of concrete, a dent is formed on the laying surface in order to prevent cracks and the like, and in this med portion, strong bonding by the adhesive of the sheet is performed. The sheet cannot easily be peeled off from the medial part, and the sheet has a predetermined thickness and rigidity. Even when there is, it is extremely difficult to attach the sheet along these curved surfaces and irregularities.

Further, in the third method, the outlet of the storage tank is opened and closed intermittently by the opening and closing body,
Although a quadrangular prism or truncated pyramid-shaped projection can be formed on the line, it is impossible to form a cylinder or truncated cone as seen in the block or plastic sheet.

The present invention has been developed in view of the above circumstances, and an object of the present invention is to provide a line having projections of a desired shape in a simple, reliable and robust manner on a laying surface at a construction site. An object of the present invention is to provide a line laying method and a line structure that can be laid.

[0009]

According to a first aspect of the present invention, there is provided a line laying method in which a line paint V is caused to flow down from a flow outlet of a paint storage tank 2 onto a laying surface C to form a line main body L1. Before the line paint V forming the line body L1 is cured, a porous sheet S having projections P is laid on the line body L1 so that a part of the line paint V is porous. While exuding on the quality sheet S,
Fixing the porous sheet S on the line main body L1 by curing the line paint V.

According to the above line laying method, the laying surface C
Before the line paint V of the line main body L1 laid thereon is cured, the porous sheet S on which the protrusions P are projected is placed on the paint V, and the paint S is placed on the upper side from the hole of the sheet S. V oozes out, the paint V is cured, and the sheet S is joined and integrated on the laying surface C together with the line main body L1, thereby forming the line L for guiding the visually impaired on the laying surface C, It can be formed simply and reliably without the need for excavation work or the like. Further, since the porous sheet S has flexibility, the porous sheet S can follow a laid surface C having a curved surface or an uneven surface which is difficult with a conventional plastic sheet. L can be reliably and firmly formed. Further, the protrusion P
Can be easily formed by placing a mold for forming a projection on the sheet S and pouring a resin material into the mold. By arbitrarily changing, the projection P having a desired shape can be formed on the sheet S without specifying the shape of the projection as in the related art.

The line structure according to the second aspect has a line body L1 formed of a line paint V flowing down on the laying surface C, a projection P, and the paint V when the paint V is not cured. V comprises a porous sheet S capable of oozing out,
The porous sheet S is fixedly integrated on the line main body L1 by the curing of the paint V that seeps into the porous sheet S.

According to the above line structure, the sheet S
By fixing the paint V and the paint V, the visually impaired person guiding line L can be formed on the laying surface C simply, reliably, and firmly.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a line L for guiding a visually impaired person laid on a laying surface C such as a road surface, and this line L is for a line flowing down on the laying surface C. Line body L colored in a bright color such as yellow formed by paint V
1 and a porous sheet S having projections P and capable of seeping out the paint V when the paint V is not yet cured. The curing of the paint V that seeps into the porous sheet S causes the line body L1 to harden. The porous sheet S is fixedly integrated on the upper surface.

As the coating material V for forming the line body L1, one having the following composition table is preferably used.

[0015]

[Table 1]

As the thixotropic materials (thixotropic materials) shown in Table 1 above, ie, thixotropic materials, colloidal silica,
Examples include hardened oil fatty acid esters, metal soaps, bentonite, and the like.

Examples of the binder include a thermosetting resin such as an epoxy resin and an acrylic resin, a petroleum resin for traffic paint, a rosin-modified maleic resin, a thermoplastic resin such as a vinegar-polyethylene copolymer, and a mineral oil. General plasticizers such as phthalic acid esters can be used.

Further, as the pigment, general pigments such as titanium oxide, ultramarine blue, graphite and other organic pigments can be used.

As the filler, general fine-grained aggregates such as silica or calcium carbonate ore having a small particle size of 1 mm or less, carbon char (heavy calcium carbonate powder), silica stone powder, talc, etc. are used. . The coating material V is not limited to a heat-melting material, but may be a room temperature-curing material.

Further, as the porous sheet S laid on the paint V, for example, the one shown in FIG. 2 is used.
The sheet S is formed by bonding and integrating a plurality of projections P in a predetermined arrangement on a base cloth S1 having a large number of holes. Such a porous sheet S is manufactured in advance in a factory in a long form, and the sheet S is carried to a construction site and cut according to the length of the line L for guiding the visually impaired person. Then, as described later, the line main body L1 laid on the laying surface C is provided.
By placing the cut sheet S on the paint V before the paint V is cured, the paint V oozes out from the holes of the sheet S to the upper side, and the curing of the paint V is stopped. The sheet S is placed on the laying surface C together with the line body L1.
The line L for guiding the visually impaired is formed on the laying surface C by joining and integrating the above.

As the base fabric S1 of the sheet S, a non-woven fabric made of polyester, rayon, nylon, or the like, or a porous net product such as a plastic net or gauze is used. Since the sheet S made of such a porous material is rich in flexibility, it can follow a curved surface or an uneven laying surface C which is difficult with a conventional plastic sheet. By laying the sheet S well, the line L for guiding the visually impaired person can be reliably and firmly formed.

The projections P provided on the base cloth S1 are:
As the molding material, the line paint V shown in Table 1 was used.
In addition, for example, epoxy resin, acrylic resin, or a mixture of a vinegared polyethylene copolymer and a coloring pigment or a filler may be used.
The projection P is formed, for example, to have a diameter of 35 mm and a height of 5 mm. In addition, in the embodiment of each figure, the projection P is shown as a frusto-conical shape that gives a warning to a visually impaired person.
Streaks P for guiding a visually impaired person may be bonded and integrated in parallel to the sheet S.

When manufacturing the porous sheet S, as shown in FIG. 3, a mold 5 having a plurality of truncated conical mold holes 51 is used, and the mold 5 is attached to the base cloth. By mounting on the S1 and pouring a resin material into the mold hole 51 and removing the mold 5 after the resin material has hardened,
The sheet S having the frusto-conical projections P projecting from the base cloth S1 can be easily manufactured. At this time,
By using the mold 5 having a different shape of the mold hole 51, a projection P having a desired shape can be formed on the base cloth S1 without specifying the shape of the projection as in the related art.

If it is necessary to prevent the outer surface of the projection P from slipping, an aggregate having a particle size of 0.1 to 2.0 mm is dispersed and fixed before the resin material is cured. Alternatively, the surface of the projection P may be pressed with a pressing die to finish it in an uneven shape.

FIG. 4 shows a line L for guiding the visually impaired.

The shutter 4 is connected to the traveling device 1.
The shutter 4 is opened and closed by operating the operating handle 14 back and forth so as to be able to swing back and forth.

Next, a method of laying the line L for guiding the visually impaired using the above laying device will be described. First, while the traveling device 1 is traveling, the operation handle 14
The shutter 4 is opened through the opening of the storage tank 2 by opening the downflow port 31 of the frame 3.
The line paint V contained therein flows down onto the laying surface C to form the line main body L1.

Before the paint V of the line body L1 is hardened, a porous sheet S having the projections P is laid on the line body L1 so that the porous sheet S is formed on the upper side of the hole of the sheet S. The paint V oozes out, and thereafter,
When the paint V is cured, the sheet S is joined and integrated with the line body L1 on the laying surface C, and the line L for guiding the visually impaired shown in FIG. Therefore, it can be formed easily and reliably.

[0030]

As described above, according to the line laying method of the first aspect, the line main body L laid on the laying surface C is provided.
Before the line paint V is cured, a porous sheet S having projections P projecting thereon is placed on the paint V, and the sheet S
Of the paint V to the upper side from the hole of the paint V
